The use of immersive virtual reality as a design input tool has the potential to dramatically alter the way students approach the design process by providing students with improved spatial understanding of their design decisions. This paper presents the findings of a case study examining the use of immersive virtual reality to assist landscape architecture students in designing a micro park. The results of the study found that students found virtual reality to be a powerful design tool for helping them understand their design decisions and enabling them to rapidly prototype their design ideas. However, issues of scale and fidelity presently limit the ability to implement the use of immersive virtual reality as a design input tool in a widespread manner.
